Answer:

Some breeds of dogs are predisposed to certain types of cancer. For example, Golden Retrievers, Boxers, German Shepards and Rottweilers are predisposed to lymphoma. Goldens and Shepards are also predisposed to hemangiosarcoma, while Rottweilers, Shepards, and Greyhounds are at higher risk for bone cancer. Boxers, pugs, Boston terriers, and other short-face dogs are predisposed to mast cell tumors. Genetic tests for cancers in these breeds are not commonly performed, but they have been looked into in some research.
